PAUL À MAYERLING, UN PORTRAIT (2025/Ita)
Directed by Antonio Pettinelli
Music by Ersilia Prosperi

LA HUESERA (2025/Esp)
Directed by Laura Suárez
Music by Ersilia Prosperi

Music by Ersilia Prosperi
Prosperi’s dreamscapes cover the romantic entanglements of octopi, nests and nations turning from safe havens to violent cages, mourning doves with gigantic human babies, and a funereal brass band mourns NATO’s deadly war games poisoning Sardinia’s land and waters.

Recorded and mixed at Angelo Mai, Kappa Bit Studio, Rome, Italy. Produced by Amy Denio, mastered by Steve Turnidge (Seattle -USA), published by Spoot Music (USA), Folderol Records (Italy). Cover Graphics by Resh Zeni.
The Mediterranean genius of chamber jazz anarchists OU (egg in Sardinian language) shines with the fury of fission on their newest release Uranio (Folderol / Spoot Music). Inventive composer and multi-instrumentalist Ersilia Prosperi has created an abundant cornucopia of spirited sounds exploring and celebrating all corners of the world, sung in a variety of romantic languages. Since their inception in Rome Italy in 2013, OU has transformed into a royal cOUrte. Ersilia holds the baton and scepter as the King, Producer Amy Denio is Regina (the queen); bassist and mix engineer Claudio Mosconi is the Prince, drummer Cristiano de Fabritiis is the Illegitimate Prince, Marchese Andrea Pesce plays keys, and vocalist Valeria Sturba plays violin and theremin.
The video is dedicated to the A Foras movement and to all the activists fighting against NATO bases in Sardinia, to the Sardinian people, and to all the peoples fighting to protect the sea and the land from abuses and barbarism. The video was shot in Quirra (Sardinia), the largest NATO base in Europe – Filmed and edited by Luca Gaetano Piras.
